Opaganib (ABC294640) 是选择性和竞争性的鞘氨醇激酶 2 (SK2) 抑制剂，Ki 为 9.8 μM。

M-25 is a Smoothened antagonist and inhibitor of the Hedgehog pathway.

ABC294640, also known as Opaganib, is an orally available, aryladamantane compound and selective inhibitor of sphingosine kinase-2 (SK2) with potential antineoplastic activity. Upon administration, ABC294640 competitively binds to and inhibits SK2, thereby preventing the phosphorylation of the pro-apoptotic amino alcohol sphingosine to sphingosine 1-phosphate (S1P), the lipid mediator that is pro-survival and critical for immunomodulation. This may eventually lead to the induction of apoptosis and may result in an inhibition of cell proliferation in cancer cells overexpressing SK2.
